Sql server 如何使用SQL查询获取此输出

我需要帮助

我有这张数据表作为说明。（有很多不同的数据行，不同的客户。请在回答中考虑这一点）

我希望它仅显示类别

实际

（第5行），包括透视类别上的

RowID

，如下所示

这应该是输出

RowID   Customer Date     Week1  Week2  Week3   Week4   Actual  Forecast
   5    Cust1    Jun-11   10     20     30      40      200     100

任何帮助都将不胜感激

提前谢谢

我试过了，但它给了我这个我不想要的

RowID   Customer Date     Week1  Week2  Week3   Week4   Actual  Forecast
   1    Cust1    Jun-11   10     null   null    null    null    null
   2    Cust1    Jun-11   null   20     null    null    null    null
   3    Cust1    Jun-11   null   null   30      null    null    null
   4    Cust1    Jun-11   null   null   null    40      null    null
   5    Cust1    Jun-11   null   null   null    null    200     null
   6    Cust1    Jun-11   null   null   null    null    null    100

PIVOT

可以，但之后需要

GROUP BY

和

SUM

---

或者，您可以在所有不同的代码条件上进行自联接，但与使用PIVOT将值列表放在一个位置相比，它的可维护性可能稍差。

您可以这样做：

    SELECT
        RowID,
        Customer,
        Date,
        (SELECT Figure1 FROM sotest WHERE Customer = 'Cust1' AND Date = 'Jun-11' AND Category = 'Week 1') AS Week1,
        (SELECT Figure1 FROM sotest WHERE Customer = 'Cust1' AND Date = 'Jun-11' AND Category = 'Week 2') AS Week2,
        (SELECT Figure1 FROM sotest WHERE Customer = 'Cust1' AND Date = 'Jun-11' AND Category = 'Week 3') AS Week3,
        (SELECT Figure1 FROM sotest WHERE Customer = 'Cust1' AND Date = 'Jun-11' AND Category = 'Week 4') AS Week4,
        (SELECT Figure1 FROM sotest WHERE Customer = 'Cust1' AND Date = 'Jun-11' AND Category = 'Actual') AS Actual,
        (SELECT Figure1 FROM sotest WHERE Customer = 'Cust1' AND Date = 'Jun-11' AND Category = 'Forecast') AS Forecast

    FROM
        sotest

    WHERE
        Customer = 'Cust1'
        AND Date = 'Jun-11'
        AND Category = 'Actual'

应该很容易封装到存储过程中，您可以在其中传递CustomerID和Date参数。

尝试基于两个参数的解决方案（
@MyCustomer
&
@MyDate
）：

基本思想是在
src
派生表中只筛选pivot所需的行和列，不多也不少。

您尝试过pivot命令吗？使用数据透视表，我已经添加了数据透视的结果。在上述问题中添加。但这不是我想要的。有什么帮助吗？你试过pivot命令吗？使用数据透视表，我已经添加了数据透视的结果。在上述问题中添加。但这不是我想要的。有什么帮助吗？
DECLARE @MyCustomer VARCHAR(10) = 'Cust1'
